    a=7

    Step-by-step explanation:

    To solve the equation, combine like terms and use inverse operations to rearrange the terms across the equal sign.

    7 (a-2) - 6 = 2a+8+a Distribute into the parenthesis

    7a-14-6=2a+8+a Combine like terms on each side of the equal sign

    7a-20=3a+8 Use the inverse operation of + 20

    7a = 3a + 28 Use the inverse operation of - 3a

    4a = 28 Use inverse operation of dividing by 4

    a=7
